Hamiltonian field theory of ferrohydrodynamics

Journal of Chemical Physics, 2011
A Hamiltonian field theory of ferrohydrodynamics is derived, with dissipation included by use of a Rayleigh dissipation function. It is shown that kinematic assumptions on the behavior of magnetization under displacements of a volume element of fluid leave a certain freedom in the construction of dynamical equations describing the time-dependence of ...

Ferrohydrodynamics

Physics of Fluids, 1964
A phenomenological treatment is given for the fluid dynamics and thermodynamics of strongly polarizable magnetic fluid continua in the presence of nonuniform magnetic fields. Examples of the fluids treated here have only recently been synthesized in the laboratory.

Directions in ferrohydrodynamics (invited)

Journal of Applied Physics, 1985
Ferrohydrodynamics treats the flow and thermodynamics of magnetically polarizable fluid in response to applied magnetic field. Following its introduction twenty years ago, ferro-hydrodynamics has developed as a branch of mechanics similar to magnetohydrodynamics and electrohydrodynamics.

Stress Boundary-Conditions in Ferrohydrodynamics

Industrial & Engineering Chemistry Research, 2007
Although much study has been devoted to the fluid magnetic behavior (i.e., ferrohydrodynamics) of the ultrastable, colloidal, magnetizable fluids that are known as ferrofluids, the appropriate stress-boundary conditions for a magnetically unequilibrated medium are lesser known.

Ferrohydrodynamic thrust bearings

International Journal of Engineering Science, 1979
Abstract This paper treats thrust bearings in which the lubricant is a ferroliquid confined by an applied magnetic field to the gap between two plates, one fixed and one mounted on a rotating shaft carrying an axial load. For plates with plane, parallel surfaces, the lubricant extends beyond the edges of the plates and axially along their sides ...

Ferrohydrodynamic relaxometry for magnetic particle imaging

Applied Physics Letters, 2011
The ferrohydrodynamic properties of magnetic nanoparticles govern resolution and signal strength in magnetic particle imaging (MPI), a medical imaging modality with applications in small animals and humans. Here, we discuss the development and key results of a magnetic particle relaxometer that measures the core diameter and relaxation constant of ...

Interfacial parametric ferrohydrodynamics

Journal of Applied Physics, 1975
When a time−periodic magnetic field with a strong gradient is imposed tangentially at the interface of a ferromagnetic liquid, parametric surface instability may result. Under typical conditions this instability grows to a certain amplitude, where nonlinear dynamic effects become dominant, resulting in a standing−wave pattern.

Surface phenomena in ferrohydrodynamics

Acta Astronautica, 1980
Abstract Various models are constructed to describe magnetic fluids. A system of equations governing the behaviour of a magnetizable medium in electromagnetic fields is written. The medium is assumed to consist of several phases and components, each one having its own temperature and being magnetized in compliance with its own law.
